Abstract
ACCORDING to the report on seismology for the year ended December 31, 1941, which has recently been received from the acting director, R. C. Hayes, the total number of earthquakes reported felt in New Zealand during 1941 was 107, the smallest number in any year since 1928 (Dominion Observatory Bulletin No. R.27, extracted from the Annual Report of the Department of Scientific and Industrial Research, 1941-42, Dominion Observatory, Wellington, New Zealand). The earthquakes, in addition to being reported by numerous individuals as having been felt, were recorded by instruments as follow, the situation of the instrument being given first, and the type of instrument in parenthesis afterwards: Auckland (Milne-Shaw), Arapuni (Milne), Rotorua (Jaggar), Tuai (Wood-Anderson), New Plymouth (Wood-Anderson), Hastings (Jaggar), Bunnythorpe (Jaggar), Wellington Central Station (Galitzin-Wilip, Milne-Shaw, Wood-Anderson, Jones, Imamura), Ta-kaka (Imamura), Greymouth (Jaggar), Christchurch (Galitzin three components, Wood-Anderson), and Monowai (Jaggar). Milne-Shaw seismograph No. 36 was installed at the Auckland Museum early in April. However, it was not until November that the necessary apparatus was obtained for maintaining accurate time. There was considerable delay in establishing a Wood-Anderson seismograph at Kaimata near Grey-mouth owing to the war, but some progress has been made. The public works officials at Rotorua have developed a method of obtaining records on blueprint paper instead of on smoked cardboard. The seismograph at Chatham Islands has been temporarily suspended owing to the War.
